Question

ii. answer these:

1. the part of the atom that carries no electric charge
2. the part of the atom that carries a positive charge
3. the part of the atom that carries a negative charge
4. the number of electrons that can be held in the first orbit (closest to the nucleus)
5. the number of electrons that can be held in the second orbit
6. the number of electrons that can be held in the third orbit
7. there are the same number of these two particles in an atom
8. the atomic number is the same as the number of these particles

draw your own model of an atom with eight protons, eight neutrons, and eight electrons (an oxygen atom).

Explanation:

1. Neutrons are neutral particles in the atom.
2. Protons have a positive charge.
3. Electrons carry a negative charge.
4. The first electron orbit (K - shell) can hold \(2\) electrons.
5. The second electron orbit (L - shell) can hold \(8\) electrons.
6. The third electron orbit (M - shell) can hold \(8\) electrons (for simplicity in basic atomic structure, in a more detailed sense, it can hold up to \(18\) but in simple models for elements like oxygen, we consider the octet rule for outer - shells).
7. In a neutral atom, the number of protons and electrons is the same.
8. The atomic number is equal to the number of protons.

Answer:

1. Neutrons
2. Protons
3. Electrons
4. \(2\)
5. \(8\)
6. \(8\)
7. Protons and electrons
8. Protons
